It’s sort of a futuristic Hobbit house.
You can see more pictures here, where it’s called the Peka Peka House.
Too cool! The shipping container house was cool, saw the episode for that one. But this one rocks! 
I want one!! It’s beautiful!
Gorgeous! How much would something like that cost? Not that I’d even think I could…just curious.
It’s apparently “Sol-e-Mer” house, at Peka Peka Beach. Very nice. More info on the house and architect here.
